RELATED APPLICATIONS

This application claims priority to U.S. Provisional Application 61/694,660 filed Aug. 29, 2012, herein incorporated by reference.

BACKGROUND

Reversible joining of various pieces of furniture, e.g., tables, has been accomplished by mechanisms or devices including at least slide locks, clamps, and dowels. A challenge to reversible furniture joining is speed of assembly and precision.

Dowels have been used in the model train area field for alignment of the modules to each other and maintaining that alignment from assembly to assembly. In these instances, track joiners have been required for a train to run smoothly over the joint between two sections. Generally, there has not been a means of stability tied to the module itself. This allows movement between sections. Modules are usually pulled together with bolts or clamps with very low fit tolerance.

Model railroad scales include from smallest to largest, Z, N, TT, HOn3, HO, OO, S, On30, O, G. The scale represents the ratio of the model to life-size. Z is 1:220 scale; N is 1:160 scale; TT is 1:120; HOn3 and HO are 1:87.1 scale; OO is 1:76.2; S is 1:64; 0 and On30 (O scale narrow gauge) are 1:48 scale; and G scale is 1:22.5 to 1:29 scale. Gauge represents the distance between the rails. Track gauge is usually 48 inch 8½ inches. HOn3 is HO scale, narrow gauge, 36 inches between the rails.

A reversible mechanism for joining furniture that is quick, sturdy, and provides a flush surface is greatly needed. In the model railroad area, a mechanism or system is needed that offers the above and does not require track joiners.

Example

Examples and methods of use are described herein as a basis for teaching one skilled in the art to employ the disclosure in any appropriate manner. These examples disclosed herein are not to be interpreted as limiting.

An embodiment of the disclosure is a system that allows for the precise alignment of various application modules for the construction of model railroad layouts. Lateral or vertical movement between the modules damages or destroys the track sections between the modules. The use of alignment dowels combined with a cam locking device integral to the module prevents movement between modules tremendously reduces or eliminates damage from lateral or vertical movement.

The mating pieces are precisely milled and aligned by dowel pins drawn together by means of a cam locking device. The system allows for the easy disassembly and reassembly of modular model railroad layouts without the usual need of joiner rails between modules.

In an embodiment, the disclosure includes but is not limited to a cam locking device 102; male dowel connections 104; male module end piece (“male MEP”) 108; female module end piece (“Female MEP”) 110; side rails 108; hard bed 114; and a soft bed 116. FIG. 1A-1C.

Each standard run module piece consists of two side rails 108 held together with a male and female module end piece 112, 110. The male MEP 112 and female MEP 110 are made to join with a high degree of precision. The male dowel connections 104 are used for alignment and a cam locking device 102, 120 is used for joining pressure. The modeling bed (the area between the previously mentioned parts) 118 is attached via gluing and fitting in mortised and rabbeted areas of the male MEP 112, female MEP 110, and side rails 108.

The standard run module can be used alone for “Z Scale” coffee table modeling or can be joined together for whatever size layout you desire in any scale. If the layout is set up to NMRA (National Model Railroad Association) standards, it is possible for the modules to be assembled in different configurations. The high tolerance fit of the modules allow the topside to be flush with each other regardless of the order they are assembled and fastened together with an integral cam lock to secure them.

The Module End Pieces (MEPs) 112, 110 are milled to a 1⅜ inches height×3 inches width×22½ inches length stock. A slot for the male cam locking device 102 is milled into the 1⅜ inches edge as well as a ⅝ inch hole 106 for the male dowel connections 104. In an embodiment, the spacing of the male dowel connections 104 is from the center. In an embodiment, the dowel connections will be 8 inches apart center to center on a 12 inch wide module. The holes 106 are centered in the edge of the stock.

The female Module End Piece (MEP) 110 is made from the same dimensioned stock and a slot is milled for the female cam lock piece 120 and ⅝ inch holes 106 are bored to accept the dowels from the male pieces at 3 inches from the edges. The side rails 108 are laminated material that is 2⅜ height, ¾ width and 47¾ inches long. The side rails 108 are then attached to the male MEP 112 and female MEP 110.

The modular system allows for the rapid setup and teardown of portable model railroads. By the use of integral alignment dowels including male dowel connections 104 and female dowel connections 106 and cam locking devices 102, 120, the need to carry loose fastening pieces is eliminated. With integrated legs 210, the layout can be set up by one person and eliminates the need to carry leg sections. In an embodiment, the reversibly connectable system may be used for a model railroad holiday display in a lobby, restaurant, department store, or home.

In an embodiment, a locking hinge system 1032 is used to folding legs in a tight pattern. In an embodiment, the leg length is 34½ inches resulting in a standard module height of 36 inches. In an embodiment, the legs 1010 are made from beech wood, a durable hard wood that resist warping.

The male MEP 112 and female MEP 110 are rabbeted or mortised depending on the design and the side rails 108 are mortised to accept the hard bed material 114. These parts are assembled in an assembly jig to maintain specs and tolerances. The soft or modeling bed can be made of different materials.

The male MEP 112, female MEP 110, and side rails 108 are milled to a high dimension tolerance enabling the modules to conform to standards. The integral leg assembly is optional as the units may be placed flat on the floor or sawhorses or other support devices.

The use of alignment dowels including male dowel connections 104 and female dowel connections 106 combined with a cam locking device 102, 120 integral to the module prevents movement between modules therefore tremendously reducing or eliminating damage from lateral or vertical movement. The modules are lined up with their proper mating ends and the locking wrench is inserted into the cam locking device hole. The pieces are pushed together by hand as much as possible and the cam lock is turned to close the distance between the modules.

Other modules in the design include a breakout module allowing modules to be attached perpendicularly. An end module allows the attachment of modules running side by side. Left and Right hand modules allow left and right hand turns. End caps allow joining of parallel runs. Angle modules allow for 22.5 and 45 degree deviations. Custom modules allow a combination of configurations using the same module.
